On April 4th, 1975, two young programmers named Bill Gates and Paul Allen formed a partnership called “Micro-soft.” Gates was 22 years old at the time and Allen was just 19. The two young men had been friends since attending high school together in Seattle and after Allen took a job with MITS in Albuquerque, New Mexico in January 1975, Gates dropped out of his sophomore year at Harvard and moved to Albuquerque to form what would later become Microsoft. The pair moved from New Mexico to Bellevue, Washington in January 1979, and Microsoft would go on to incorporate on June 25th, 1981. The first Microsoft-powered IBM PC was unveiled later that year running Microsoft’s 16-bit MS-DOS 1.0 operating system, and the rest as they say, is history. Gates and Allen’s Microsoft went on to drive the personal computing boom that has taken place over the past three decades, and the firm’s upcoming Windows 8 OS looks to continue what the company’s founders started through the post-PC era and beyond. Happy birthday, Microsoft.
